Hi,One of my two 32v battery banks which is under the control of a 32v outback inverter/charger can cranck the engine on, however if I turn off the charger and run the inverter for 10 minutes consuming only 400 watts, then this bank can barely move the starter motor. So I figuered a new bank should be installed. Before doing this heavy proposal (more concerned about the weight of the batteries rather than the cost), I would like to try to equalize the batteries using the outback. I know for sure that I don’t have any dead cells.
Can someone with similar charger please share their settings for the equalization, including the process?
Do you think I can bring this bank back to live?
This bank charges quickly and discharges quickly too, but remember it still can turn the engine on if it is just off the charger. So according to what I have read, it has a surface charge due to over sulfating which is usually reversible.
Thanks

Re: Outback 32v owners....help please
How old are the batteries?
Did you measure the cells with a proper hydrometer? Whats their specific gravity?Scott

Re: Outback 32v owners....help please
Also I am planning on using the 8V195 instead of the 819. Any objections anyone?

Maintenance is before the problem got this bad. Id replace them and move on. 819 batteries are heavy and not cheap. Equalize them every few months and they may last longer.

My boat is 12 volt. I replaced the 8 volt batteries on a 52c a while back and hated every heavy minute of it.

Why not try to equalize them before you replace? It doesn't take much effort. Just select the equalize function on the Outback. It will bring the bank up to 40v for two hours. Make sure you fill them with water first as they will boil some off during the process.
